The contents of vitamin D3 and 25-hydroxyvitamin D3 in different varieties of dairy products in Russian market

Vitamin D has received global attention because of its many health benefits. Although there is general agreement about the importance of vitamin D for bone health, there remains skepticism about the nonskeletal health benefits of vitamin D. There is general agreement that vitamin D deficiency is a worldwide health problem. This is due in part to a lack of appreciation that sunlight is an important source of vitamin D. Recent findings in western countries have made new recommendations for vitamin D intake to prevent vitamin D deficiency. Vitamin D deficiency is defined as a 25-hydroxyvitamin D3 level below 20 ng/ml and vitamin D insufficiency is defined as 21-30 ng/ml. This research focuses on the reasons for vitamin D deficiency and demonstrates the results of the contents of vitamin D3 and 25-hydroxyvitamin D3 in dairy products including natural and pasteurized goat milk; natural, baked, and pasteurized cow milk; fortified cow milk (pasteurized and ultra-pasteurized); butter; homemade butter; and butter made from baked milk (ghee). The greatest concentrations of vitamin D3 and 25(OH)D3 in milk were discovered in goats' milk, according to our findings. Generally speaking, the larger the quantity of butter in a recipe, the higher the concentration of Vitamin D3 and 25(OH)D3.
